Flip Inner Segment If String Starts and Ends With Vowels

Given an array of strings arr, transform each string s as follows and return the resulting array: If both the first and last characters of s are vowels, reverse (mirror) the inner substring of s (i.e., s[1:-1]) and then concatenate it back with the original first and last characters. Otherwise, keep s unchanged. Vowels are a, e, i, o, u in both lowercase and uppercase. Input Line 1: integer n (array length) Next n lines: one string per line Output Print n lines, each the transformed string. Constraints 1 <= n <= 2*10^5 Total length of all strings <= 2*10^5 Example Input: 4 apple abca a xyz Output: alppe acba a xyz Example Input 4 abca xyz a AeIoU Output acba xyz a AUoIe
